OBITUARY.
Mr. Timothy STILES departed this life on Thursday afternoon, the 27th day of February, 1879, in the 68th year of his age. He was born in ?oga county, Penn. June 6th ,1811. At an early age he removed to Steuben co., N.Y. and was there married to Hannah SHAW on the fifth day of Dec. 1831. They removed to Waitesville, Alleghany Co. N.Y. some time during the year 1837 where they resided until the spring of 1855 and being engaged in the cabinet business, and latterly, during the last four or five years of his stay there in the mercantile business. His continued failing health and the hope of being better able to provide for his family induced him to come west, and in the spring of 1855 he removed, with his family to Postville, Iowa, where, for some years, he engaged in farming and with his general health much improved.

Finding farming uncongenial to his tastes and most of his family having left home to do for themselves, he concluded to dispose of his farm. In 1863 he sold his place and removed to Postville where he built himself a pleasant home, fixed up with much care for their comfort in their declining years. In the spring of 1875 a dark cloud overshadowed his life in the death of a faithful and devoted and affectionate companion. Here, again, his health began to fail him, but he gradually reacted and responded enjoying an unusual degree of health up to within a short time [illegible] sickness.

On the first of May last he became united in marriage to Miranda MEKELLAND [surname may be McKelland] with whom he lived happily, and looked forward to years of enjoyment. But no ties are too sacred for the [illegible]. He was unwell for some time previous to the final sickness but supposed it would wear away. The attack was ushered on with a violent chill, followed by extensive vomiting from which he never recovered. His physicians at first gave their opinion that the trouble was inflammation of the mucous membrane of the stomach, but a more careful diagnosis induced the conclusion beyond a doubt [illegible words] and no hope was given. He suffered terribly during the better part of his sickness, but he was very patient and resigned, and willing and ready to die. He frequently asked the question, "Am I not getting near thy rest? How soon will I be there?" His anxiety to depart seemed to grow stronger as he neared his end. Every attention and care that affection and medical skill could suggest to make life more easy was given him. His mind was perfectly clear and collected up to within a short time before his death. Two weeks and five days from the time he was taken sick, he was taken home, where all is rest and peace. He frequently expressed his faith in a happy immortality beyond. [remainder illegible]
